Ok, give me biden. Where are his lists of corruption scandals[1]? His public statements about taking bribes?
I'm not quite sure how to explain this very obvious point: biden and his government was not corrupt in any meaningful sense and trump and his government is extremely corrupt and pretending that they're the same is both factually wrong and has the effect of protecting trump and his corruption.
The point isn't that anyone is above reproach, the point is that all you're doing is normalizing the increased awfulness of the republican corruption. And normalizing it means that it is more likely to continue happening and less likely to be punished.
If you're supposedly unhappy about clinton "corruption" why aren't you really mad about trump?
This whole "oh everything is the same nothing can improve" attitude is literally a favored tactic of the most corrupt governments. They want you to think that way because it means they'll never be held accountable. Any time people start talking about improving things they're met with an endless deluge of "oh it's all the same nothing can change" which is, of course, a self-fulfilling prophecy.
[1] The best the fairly obvious house republican "investigation" into joe biden could manage was some vague statements about his son getting paid for having the last name biden, which may or may not be illegal, but certainly seems unethical, but more importantly, ISN'T THE SITTING PRESIDENT OF THE UNITED STATES. Like, it is so incredibly obvious that words fail me that the president being corrupt matters A LOT MORE than his son being corrupt. Like, a lot a lot a lot more.
